Is the one that works for you.
Before you can declare your efforts a success or failure, you need to know what you want to measure and why.
What I do for myself is different from what I was doing when I worked for a multi-million dollar internet retailer.
When I worked for them, I saw that they had lazy and inappropriate goals for their social media efforts.
So in 3 weeks in April 2013, I met the goal they set for the rest of the year and then started doing work that really mattered.
My own work, for myself is what you are reading right now. I don’t have a goal of hundreds or thousands of readers, followers, friends, likes or whatever.
Yes, I have those, but that is as a result of my efforts over time, not because a big following was my goal.
For nearly every unbreakable rule, I can find someone who is breaking it and still is happy with their success.
The first step in doing anything is knowing your “why”. Then do it.
